PROBLEM TO BE SOLVED: To provide a circuit board which can improve a solder life than before.SOLUTION: A circuit board (10) has an electronic component (12) and a solder (13). The electronic component (12) includes: a printed circuit board (11) having a land (21) on one surface (11a); a main body section (30) arranged on one surface; and an electrode (31) provided in an opposite surface (30a) of the one surface in the main body section. The solder (13) electrically connects the land and the electrode with each other. Hole sections (22, 36) are formed on one surface of the printed circuit board and the opposite surface of the main body section, and protrusion sections (32, 25) are formed on the other side which are inserted in the hole sections, and brought into contact with a member having a hole section to be supported, in the inserted status. The protrusion sections have insertion sections (27, 33) arranged in the hole sections and spacer sections (28, 34) which are arranged outside of the hole sections and keep a predetermined interval between the land and the electrode. |
